Toledo, a former member of the PGA Tour, fired a 6-under 66 and Gove posted a 4-under 68 in windy conditions.
Jon Mills and Kris Cox both shot rounds of 3-under 69 and are knotted in fourth place at minus-9.
Wilkinson opened on the back nine Friday and parred his first eight holes before a birdie at the par-5 18th. He added another birdie at the third, then made back-to-back par saves at six and seven, from six and 12 feet, respectively.
Wilkinson joined the leaders with a 6-foot birdie putt at the par-5 ninth.
'I played pretty well considering conditions,' said Wilkinson. 'It's nice to be 10-under. I didn't put myself in those positions, but the closer you are to the lead, the better the chances.'
Toledo, who won this year's Lake Erie Charity Classic at Peek 'n Peak Resort, rolled in a pair of 10-foot birdie putts at 10 and 11, his first two holes on Friday.
He tallied three more birdies on his opening nine, then birdied the fifth to reach 10-under par for the tournament. Toledo missed a 10-footer to save par at the sixth, but birdied No. 9 to share the lead.
'I really like the course,' said Toledo, who reunited with the same caddie that was on the bag when Toledo won earlier this season. 'I feel good for tomorrow.'
Gove had an up-and-down round with four birdies, two bogeys and a double-bogey at the 11th. He caught fire at the end of his round and that's how he moved up the leaderboard.
He two-putted from 30 feet out for a birdie at 15, and hit a 4-iron to a foot to set up a birdie at No. 16. Gove knocked a 7-iron to 10 feet for a birdie at 17 and closed with his fourth consecutive birdie from 2 feet at 18.
'That's good stuff,' said Gove, who finished second to Toledo at Lake Erie. 'I feel pretty good. A couple shots got away from me, but I don't want to force it too much.'
Ryan Hietala fired a 5-under 67 on Friday and is alone in sixth place at minus-8.
Charley Hoffman (70), Jamie Broce (65), Camilo Villegas (67) and Jeremy Anderson (65) share seventh place at 7-under-par 137.
David Morland IV, who shared the lead with Wilkinson Thursday, struggled to a 1-over 73 and is alone in 11th place at minus-6.
Defending champion Jeff Quinney made the cut on the number at even-par 144.
